Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Fragment‐Based Design of Targeted Covalent Inhibitors: The Scope and Limitation of Linking Approaches

ChemMedChem, Volume 21, Issue 10, 27 May 2026.
This paper by Kollár et al. reports a covalent fragment linking study against the SARS‐CoV‐2 main protease (3CLPro). Beginning with inactive fragment hits, the application of rational linker design enabled the generation of reversible covalent inhibitors exhibiting low micromolar potency. The study details some general limitations and best practices of

Achieving Near‐Complete Dechlorination of Poly(vinyl chloride) via Electrochemical Reduction

ChemSusChem, Volume 19, Issue 10, 27 May 2026.
A one‐pot controlled‐voltage electrolysis achieved up to 97% dechlorination of poly(vinyl chloride) using common plasticizers as redox mediators. The liberated chloride ions were oxidized at the anode and utilized in a subsequent arene chlorination, offering a route for repurposing the chlorine from PVC.

Revisiting Defect‐Engineered M(III)‐Doped ZnO Photocatalysts for Emerging Pollutant Photodegradation and Mineralization: A Mini‐Review

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
Water pollution has become a major environmental concern due to industrial, agricultural, and urban activities that release various pollutants into freshwater systems. ZnO‐based photocatalysis is an effective strategy for organic pollutant degradation, but its performance is limited by rapid electron–hole recombination and weak adsorption capacity ...
